Print from emails, only works when set to color

[mike L]

I can scan and copy, set to black and white. When printing emails, the setting for color prints works. I get blank pages when set on black and white. How can I fix this first?

Windows 7
Hp 4650

The printer is a two cartridge printer. Maybe it in some settings mixes grey and black from the tri-colour cartridge and In other cases uses the black cartridge, which may not work.

So could you please upload a scan or photo of a nozzle check? I think it is called "Print Quality Report" by HP
